Data schema error on z/OS split schema upgrades from versions before Pega 7.1.8

When upgrading to a split schema on Pega 7.x with IBM DB2 for z/OS, you see an error during the data schema upgrade when the system tries to drop the PRPC_Updatescache procedure. Because triggers on rules tables use PRPC_Updatescache, you must use the ZOSDisableTriggerScripts to disable these triggers before you update the data schema.

1. Follow the instructions in the Pega 7 Platform Upgrade Guide to upgrade the rules schema, but stop immediately before you upgrade the data schema with the upgrade.bat or upgrade.sh script. The Pega 7 Platform Upgrade Guide is on the Support > Deployment Guides page.
2. Copy the contents of the <distribution>\ResourceKit\ZOSDisableTriggerScripts directory into the <distribution>\scripts\ directory.
3. Run fixZosTriggers.bat or fixZosTriggers.sh with the following arguments:
   --action preupgrade
--dataschema <data schema name>
   --oldrulesschema <old rules schema name. If you are upgrading from a single-schema system, this is the data schema name.>
   --newrulesschema <new rules schema name>
   --automaticddl <Optional. Set to true to automatically apply the disable trigger SQL scripts.>

   For example:
   fixZosTriggers --action preupgrade --dataschema pegadata --oldrulesschema pegarules --newrulesschema newrules --automaticddl false

4. If you did not set --automaticddl to true in the previous step, run the <distribution>\schema/disable.sql script to manually disable the trigger SQL scripts.
5. Run the data schema upgrade as described in the Pega 7 Platform Upgrade Guide.

Apache Ignite is no longer supported

Apache Ignite is no longer supported and has been replaced by Hazelcast Enterprise Edition 3.10 in embedded mode. If you used encryption with Apache Ignite, you can configure encryption on Hazelcast Enterprise Edition in the same way that you configured it for Apache Ignite.

For more information about encrypting nodes, see Enabling encrypted communication between nodes.

New roles required for system management features and APIs after upgrade

The pzSystemOperationsObserver and pzSystemOperationsAdministator privileges are no longer used for accessing system management features in Admin Studio and for system management APIs. Pega Platform™ has new privileges for individual system management functions and new roles configured with these privileges. Use the following roles to access system management features and APIs:

• PegaRULES:SysOpsAdministrator – has all administrator and observer privileges
• PegaRULES:SysOpsObserver – has all observer privileges
• PegaRULES:SysAdm4 – has all administrator and observer privileges

After upgrading, you can include one or more of these roles in your access group or create a custom role. For more information about access roles, see Access roles.
